Abstract:
Fast channel changing in digital-television-based entertainment networks can be implemented, for example, by electing to tune to channels at opportune tuning times. In an exemplary implementation, a method includes: receiving a channel change request that indicates a requested new channel from a client device; preparing a broadcast video data stream of the requested new channel that is offset in time behind a current broadcast time for broadcast video data of the requested new channel; and streaming the broadcast video data stream responsive to the channel change request. In another exemplary implementation, a system includes: a storage device (408A) that retains broadcast video data (410) for multiple channels; a video data extractor (416) that accesses the retained broadcast video data and retrieves an intra frame of broadcast video data that is in the past for a requested channel; and a video data distributor (418) that transmits the retrieved intra frame of broadcast video data.
Abstract:
Master communication device for a token network. The token network comprises a shared communication medium and at least one further master communication device coupled to the shared communication medium, the token network being arranged to pass frames and to execute a poll for master cycle. The master communication device is restricted in executing a poll for master cycle in specified cases especially if another device executed a poll for master for finding a new master communication device on the token network.
Abstract:
A node system includes a first node, a second node, and a supervisory node which transmit frames while increasing or decreasing the cycle microtick count, and determines reduced cycle microtick counts by subtracting or adding a rate correction limit value from or to the cycle microtick count of the supervisory node when reception of the first frame transmitted by the first node stop and the cycle microtick count of the supervisory node when reception of the first and second frames stop.
Abstract:
A network (20), especially a wireless ad-hoc network, comprising nodes (21-27) within a neighborhood and at least one token being periodically forwarded between the nodes (21-27) of the network (20) at a token interval and a method for forwarding the at least one token through the network (20) in a directed manner are provided. At each token interval, the at least one token (35) is forwarded from first nodes holding the at least one token (35) within a present token interval to neighboring second nodes, each of which is not a neighboring node of third nodes having held the at least one token (35) within a previous token interval directly preceding the present token interval.
Abstract:
A method for a first communication device transreceiving a message with a second communication device, according to one embodiment of the present invention, comprises the steps of: the first communication device confirming a user value of the second communication device; the first communication device comparing the user value of the second communication device that is confirmed to a user value of the first communication device; and the first communication device establishing either the first communication device or the second communication device as an initiator having initiative for communication and establishing the other as a responder not having initiative for communication, depending on the result of the comparison.
